A tree giant druid casts magic beneath a cosmic night sky

A detailed 2.5D fantasy epic illustration featuring a colossal rooted Tree-Giant Druid as the central subject, actively casting a powerful nature spell in a dynamic pose. The tree giant stands on a massive, moss-covered ancient root system, with its right hand extended forward, palm open, conjuring a turbulent, swirling sphere of bright emerald-green and cyan magical energy. The giant's torso and shoulders are adorned with intricately layered Druid-style armor crafted from gnarled bark-plates, living vines, and preserved deep-green leaf pauldrons. Its eyes glow with intense golden light, and a radiant sun-like power core shines from its chest. The background is a surreal, magical Zangarmarsh landscape under a cosmic night sky, filled with towering bioluminescent blue-glowing giant mushrooms, floating landmasses, and distant Draenei crystalline spires. A complex web of glowing green magical energy streamers crisscrosses the scene, connecting suspended macro double-exposure water spheres: [Foreground Spheres] Two massive, crystal-clear double-exposure water spheres rest in the immediate foreground, each revealing a vivid miniature world inside: the left sphere contains the desert fortress of Orgrimmar under a golden sun, and the right sphere contains the glowing blue crystal city of Exodar. [Midground Spheres] Three distinct double-exposure water spheres float strategically near the tree-giant, linked by green energy ribbons: one shows the lush floating islands of Nagrand, another displays the glowing fungal forests of Zangarmarsh, and the third reveals a sacred crystalline temple. Hyper-detailed textures, magical green volumetric lighting, double-exposure macro refraction effects, maximalist fantasy art style, cinematic high-contrast lighting, 8k resolution, masterpiece.
